5. Effects of Solvent and Catalysts on the Hydrogenolysis of Alkylnaphthalenes

Abstract

Hydrogen transfer from tetralin to benzyl-1-methylnaphthalenes at 450℃ was promoted by Ni and active carbon. It has been shown that one of the active carbons shows higher activities than Ni, contrasting with the hydrogenation of trans-stilbene in tetralin at 380℃. These data suggest that carbon materials can act as active catalysts promoting hydrogen transfer from hydrogen donor solvent under coal liquefaction conditions, with a lesser extent of hydrogen acceptor adsorption on them.
